If 110 volts ac is mixed up ith 12 volts dc what will be the
resultant voltage and what is the wave form?
How to dimensioning SDCCH, LAPD and CS7 signaling on GSM?
why dont we connect the two 12 V DC batteries in parallel, for an inverter (UPS)? is there any harm ?
We know that, in case if there is a faulty insulation,or sc, the current is bypassed to earth through the earth wire that has low resistance.Actually, what will happen to that current that flows through gnd?In that case,if we come in contact with that faulty appliance, wont that current flow through us as we form a closed path by standing in gnd?Is grounding a safety measure?
What the capacitor Current formula?, For 1 KVAr how amps its required? for using the KVAr for boosting the PF Design Calculation.( Eg: for 30 KVAr required how many KW?)

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
WHY DG are rated in KVA or MVA ???., but ALL power plants are rated in KW or MW.,,?
